Stunnel 4.22 compiling issues on Solaris 10
by cod3fr3ak 09 Apr '08

09 Apr '08

I have sucessfully compiled Stunnel 4.22 on Solaris 10, but still recieve the sam errors during the configure. Initially I tried using Openssl-0.9.8f from Sun Freeware. Then I built and compiled Openssl-0.9.8g, but I still recieved the following errors on the build: configure: **************************************** SSL checking for SSL directory... /usr/local/ssl checking for obsolete RSAref library... no checking /usr/local/ssl/include/openssl/engine.h usability... yes checking /usr/local/ssl/include/openssl/engine.h presence... no configure: WARNING: /usr/local/ssl/include/openssl/engine.h: accepted by the compiler, rejected by the preprocessor! configure: WARNING: /usr/local/ssl/include/openssl/engine.h: proceeding with the compiler's result checking for /usr/local/ssl/include/openssl/engine.h... yes <ftp://ftp.sunfreeware.com/pub/freeware/sparc/10/openssl-0.9.8f-sol10-sparc-…>

Using stunnel + haproxy for SSL support
by Alberto Giménez 04 Apr '08

04 Apr '08

Hi, I'm having trouble using stunnel and haproxy to load balance https and http traffic. To be honest, I really don't know wether it is stunnel or haproxy related so I am going to contact both lists :) I have set up a haproxy load balancer as http proxy for two backend Apache2 webservers. It works fine. I also have stunnel on the same LB to add SSL suport (with xforwardedfor patch installed). It works fine (mostly). The issue is related to Apache trailing slash thingie. If I query https://haproxy.domain.loc/hatest/ it works perfectly, but if I omit the trailing slash: https://haproxy.domain.loc/hatest then following things happen: - Browser makes SSL connection with stunnel on port 443. - stunnel deciphers and forwards the request on the haproxy attached to LB's port 80. - haproxy (now using plain http) forwards to one of the backends. - Apache2 located on the backend replies with "301 moved permanently" to force the browser to add the trailing slash. As Apache was queried by *haproxy in plain http*, the 301 includes http:// on the Location header. HTTPS is over from now! - The client browser then rewrites the address to http://haproxy.domain.loc/hatest/ and SSL is lost forever. I've been googling and searching the lists but nothing found, just this old message: http://mirt.net/pipermail/stunnel-users/2007-January/001437.html Has anyone found a workaround for that issue? Thanks in advance. -- Alberto Giménez

Problems with Stunnel 4.22 build
by GGrant 04 Apr '08

04 Apr '08

There's a problem with the Stunnel 4.22 build as there's undefined IDs in the resources.rc file. To get around this get the resources.rc file from an earlier build (e.g. Stunnel 4.21) and replace it. It should compile happily -- View this message in context: http://www.nabble.com/Problems-with-Stunnel-4.22-build-tp16491431p16491431.… Sent from the Stunnel - Users mailing list archive at Nabble.com.

23 secs to list 5000 files using stunnel and samba on linux
by Paul Kerin 04 Apr '08

04 Apr '08

Hi I'm using the following s/w versions on RHEL3: Stunnel: 4.04 (also experimenting with 4.22, no difference so far) Samba: 3.0.9-1.3E.10 Kernel: 2.4.21-32.0.1.EL Stunnel is used to encrypt samba connections from linux clients because redhat 3 doesn't support NTLMv2 (cifs not standard and probably not an option). To list 5000 files (simply typing ls within a mounted directory on the client) it consistently takes around 20-23 seconds to return the data. Listing is almost instantaneous when using a windows client, or using a linux client without stunnel. As a side note, if I pipe the result to /dev/null it takes around 9 seconds (?). The network forwarding path from the samba client to samba server is: smbclient > localhost:924 > stunnel > remotehost:923 > stunnel > samba server (port 446) Tcpdump shows that when using stunnel about 10500 packets are generated, minus stunnel it's more like 500. I'd expect some overhead related to SSL, but 21 times the traffic seems a little excessive. I've experimented with socket options such as TCP_NODELAY, SO_LINGER, SO_RCVLOWAT, SO_OOBINLINE, etc with no improvement at all. However, my understanding of these is pretty superficial so I'm not confident I've exhausted all options here (ie perhaps combining multiple settings at once). I've got stunnel debug set to 7 on client and server. No errors and no logging at all except for the initial handshake when the mount is created. Including the tcpdump would probably be excessive at this stage. In summary, using stunnel the data gets transmitted in packets usually containing around 200 bytes, whereas without stunnel it's mostly 1408 byte packets. Any suggestions? Thanks Paul

Hi, I've downloaded the Stunnel source code and I am trying to compile it with the Visual C++ compiler (cl.exe). I am not sure what to do as I cannot find the Makefile.w32. So how do I go about it? Also how do you apply a user patch to the source code/ Must I copy and paste the code to the required files?

Stunnel-Openssl: Problems with certificate chain
by Pietro Di Primo 31 Mar '08

31 Mar '08

Hi, My name is Pietro Di Primo and I work on the INFN Grid project (http://grid.infn.it/) I'm trying to develop an application based on stunnel. Everything works well when I use user certificates (signed by our CA), but i need to use (on the client side) a particular proxy. This proxy contains a public and a private key, and the public key of the user that generated it (I atteched a file with a such proxy). On the server side I have the CA certificate but not the user's one, so I can't verify the client (unable to get local issuer certificate). I tried to get the user certificate using the SSL_get_peer_cert_chain function on the server, but it returns NULL. On the client side I tried SSL_CTX_use_certificate_chain_file, Also I tried to get a STACK_OF(X509) and use SSL_CTX_use_certificate (for proxy certificate), and SSL_CTX_add_extra_chain_cert (to include the user's certificate), but it still doesn't work. Can you help me please? Best Regards -- --- Ing. Pietro Di Primo INFN - Istituto Nazionale di Fisica Nucleare Grid Computing Research Area Via S.

New libwrap code
by Randy McMurchy 26 Mar '08

26 Mar '08

Hi all, My apologies if this has been discussed (I've reviewed the archives since 4.21 was released), and if so please just point me in the right direction. I read in some of the messages there's been a revamp (overhaul, changes, whatever) of the libwrap code in Stunnel-4.21. I'm not having any issues using the new version, however, I'm seeing it spawn 5 processes where in every other version I've used in the past there has always only been one process spawned. Here's what I see: root 3408 1 0 17:50 pts/10 00:00:00 /usr/bin/stunnel root 3409 1 0 17:50 pts/10 00:00:00 /usr/bin/stunnel root 3410 1 0 17:50 pts/10 00:00:00 /usr/bin/stunnel root 3411 1 0 17:50 pts/10 00:00:00 /usr/bin/stunnel root 3412 1 0 17:50 pts/10 00:00:00 /usr/bin/stunnel stunnel 3413 1 0 17:50 ? 00:00:00 /usr/bin/stunnel Is this a product of the new libwrap code?

Enhancement request - Increase thread stack size
by Mccue, Richard Alan 25 Mar '08

25 Mar '08

I load an engine into Stunnel to access the private key. The engine loads without incident, but Stunnel consistently aborts when creating a session with the first peer because the thread stack is too small. I rebuilt Stunnel 4.21 on my test machine after increasing the stack size parameter and it fixed the problem. Here is the diff: --------------------- # diff -b common.h common.h_orig 33c33 < #define STACK_SIZE 32768*4 --- > #define STACK_SIZE 32768 42c42 < #define STACK_SIZE 65536*4 --- > #define STACK_SIZE 65536 --------------------- Could this enhancement be included in the next Stunnel release?

HTTPS being redirected back to HTTP
by Steven Buehler 25 Mar '08

25 Mar '08

I have tested several versions of stunnel up to version 4.21 on SLES 9 and 10. I am trying to use stunnel to implement TLS 1.0 for HTTPS on a Lotus Domino server. I am able to connect to the Domino server with a web browser with HTTPS successfully. However, once I log into the server it drops me back down to HTTP. I suspect the Domino server is sending a redirect back to HTTP during the login because if I change the URL back to HTTPS in the browser after the login, it re-establishes the HTTPS connection. I've checked with Lotus support and there is nothing that can be done on the Domino server to prevent this. Is there anyway to handle this in stunnel so that the requests remain as HTTPS requests to the browser? Here is the services section of my stunnel.conf [https] sslVersion = TLSv1 accept = gsvatestm02.er.usgs.gov:443 connect = gsvatestm02.er.usgs.gov:80 TIMEOUTclose = 0

possible stunnel memory leak
by Stefano Stabellini 25 Mar '08

25 Mar '08

Hi all, I may have found a possible memory leak in stunnel (version 4.15) when used with pthreads. What I am seeing is the memory usage going up when connections open and never going down, no matter if all the connections close. It is really easy to reproduce it: I have started two stunnel instances communicating with each other, the first one acting as a server (config file stunnel.1) and executing cat, the second one acting as a client (config file stunnel.2) and opening port 5556. Then I execute the script I have attached that simply opens 500 connections using netcat to port 5556. If you cat /proc/<stunnel pid>/status you can see that the memory usage is about 300MB. The problem is that even after all the connections are closed the memory usage stays (more or less) the same. I tried to find the bug myself using valgrind, but I couldn't get far, it seems that valgrind gets confused by openssl so doesn't print very useful informations. I really appreciate any help you can give me; just tell me if you need any other info. Best Regards, Stefano Stabellini #!/bin/bash i=1 while test $i -lt 520 do cat script | nc 127.0.0.1 5556 &>/dev/null & echo $i i=$(( $i + 1 )) done foreground = yes [test] accept = 5555 cert = /etc/ssl/certs/stunnel.pem exec = cat foreground = yes [test] accept = 5556 cert = /etc/ssl/certs/stunnel.pem client = yes connect = 5555

What is the stable version of Stunnel?
by Randy McMurchy 22 Mar '08

22 Mar '08

Hi all, Can anyone say for sure what is the stable version of Stunnel? On the main Stunnel web site page ( http://www.stunnel.org ) and in the announcement for the version it says the new 4.21 version is experimental. However, on the download page ( http://www.stunnel.org/download/source.html ) the 4.21 version is flagged as the stable version. Sort of confusing. -- Randy

I'll compile Openssl if there is no other way but I'd rather not. Any ideas? R

bidirectional tunnel
by Leo Cherepanov 14 Mar '08

14 Mar '08

Hello. First of all - thanx a lot, I'm using stunnel every day and it helps me. It will help me even more :) if I can make bidirectional tunnel between external server S and computer C behind nat-proxy-firewall. Of course, C is initiator. I mean after tunnel is up, there is a port-forward C:port1->S:port2 (already works) _and_ S:port3->C:port4 Once again, S has an external ip, C has a private ip. Is this schema posible? Thanx en avance.

It seems your files do not contain a PKCS#12 structure (containing the key and the whole certificate chain). I should have recognize this by the fact you have one file for each certificate. Sorry.

stunnel not seeing ca bundle files
by sf.techguy＠gmail.com 12 Mar '08

12 Mar '08

I'm running stunnel 4.14 on Darwin 7.0.0 (Mac OS X Server 10.4.11), with OpenSSL 0.9.71. I purchased a security certificate from comodo, and was able to get it installed and working (mostly) with stunnel, but when I browse to the website, I get an error that the the browser can't verify the identity of the site, due to a problem w/the security cert. I called comodo, and they the error is caused by stunnel not seeing the intermediate certificate files that they told me need to be installed in order for their certificate to work. These files were: ComodoUTNServerCA.crt UTNAddTrustServerCA.crt AddTrustExternalCARoot.crt EssentialSSLCA.crt my_server_net.crt I modified stunnel.conf, and included this line: CApath = ca-certs/ (<- dir path, relative to chroot, containing above files) But the error persists. Can anyone tell me if what comodo support is telling me is even correct? I've verified that my .key and .crt files match by running: $ openssl x509 -noout -modulus -in server.crt | openssl md5 $ openssl rsa -noout -modulus -in server.key | openssl md5 And the output of both matches. Not sure what to try next. Any help much appreciated! Thanks in advance...

behaviour on remote disconnection
by Marek Jarycki 11 Mar '08

11 Mar '08

Hi. I'm using 3.26 version of stunnel. How to disallow creating local sockets (on client side) when remote (server) is not available? My application detects socket creation errors and it works without stunnel, but in stunnel the socket is always opening correctly so I have to wait for timeouts to discover network disconnection. Regards, deimoss

The problem was "foreground = yes". Since xinet.d redirects stderr back over the network connection, the stunnel startup messages were going back to the client. For some reason, the client didn't think that was a proper SSL handshake. ;-) -- ======================================================================== Ian Pilcher arequipeno(a)gmail.com ========================================================================

unknown protocol error (140770FC) with xinetd
by Ian Pilcher 10 Mar '08

10 Mar '08

I am trying to set up rsync over SSL with stunnel. I've got things working when I run stunnel standalone on both systems, but I have been unable to get things working when I run stunnel via xinetd on the server (haven't tried using xinet on the client yet). Here is the (standalone) server configuration that works: cert = /etc/stunnel/rsyncs_cert.pem key = /etc/stunnel/private/rsyncs_key.pem client = no pid = /var/run/stunnel.pid RNDfile = /var/run/stunnel/random_seed foreground = yes debug = debug ;output = /var/run/stunnel/stunnel.log [rsyncs] accept = 2873 exec = /usr/bin/rsync execargs = rsync --daemon Here is the (non-working) server-side xinetd configuration: # default: off # description: rsync tunneled over SSL (stunnel) service rsyncs { disable = no flags = IPv4 socket_type = stream wait = no user = root server = /usr/sbin/stunnel } ... and the (non-working) server-side stunnel configuration: cert = /etc/stunnel/rsyncs_cert.pem key = /etc/stunnel/private/rsyncs_key.pem client = no pid = /var/run/stunnel.pid RNDfile = /var/run/stunnel/random_seed foreground = yes debug = debug output = /var/run/stunnel/stunnel.log exec = /usr/bin/rsync execargs = rsync --daemon Trying to connect to the non-working configuration with openssl s_client, I get: CONNECTED(00000003) write to 0x9b9e938 [0x9b9f068] (133 bytes => 133 (0x85)) 0000 - 80 83 01 03 01 00 5a 00-00 00 20 00 00 39 00 00 ......Z... ..9.. 0010 - 38 00 00 35 00 00 16 00-00 13 00 00 0a 07 00 c0 8..5............ 0020 - 00 00 33 00 00 32 00 00-2f 03 00 80 00 00 66 00 ..3..2../.....f. 0030 - 00 05 00 00 04 01 00 80-00 00 63 00 00 62 00 00 ..........c..b.. 0040 - 15 00 00 12 00 00 09 06-00 40 00 00 65 00 00 64 [email protected] 0050 - 00 00 14 00 00 11 00 00-08 00 00 06 04 00 80 00 ................ 0060 - 00 03 02 00 80 3e b4 89-34 c1 e6 93 97 2d 8d ca .....>..4....-.. 0070 - 90 e1 4c 51 e1 71 c7 54-ed 52 0c 6e 2e 47 90 9b ..LQ.q.T.R.n.G.. 0080 - 8e c6 73 3d d8 ..s=. read from 0x9b9e938 [0x9ba45c8] (7 bytes => 7 (0x7)) 0000 - 32 30 30 38 2e 30 33 2008.03 18523:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:s23_clnt.c:567: The server log shows: 2008.03.10 11:32:23 LOG5[18563:3086215456]: stunnel 4.20 on i386-redhat-linux-gnu with OpenSSL 0.9.8b 04 May 2006 2008.03.10 11:32:23 LOG5[18563:3086215456]: Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv6 Auth:LIBWRAP 2008.03.10 11:32:23 LOG7[18563:3086215456]: stunnel started 2008.03.10 11:32:23 LOG7[18563:3086215456]: FD 0 in non-blocking mode 2008.03.10 11:32:23 LOG7[18563:3086215456]: FD 1 in non-blocking mode 2008.03.10 11:32:23 LOG7[18563:3086215456]: FD 4 in non-blocking mode 2008.03.10 11:32:23 LOG7[18563:3086215456]: FD 5 in non-blocking mode 2008.03.10 11:32:23 LOG7[18563:3086215456]: Connection from 127.0.0.1:38481 permitted by libwrap 2008.03.10 11:32:23 LOG5[18563:3086215456]: stunnel accepted connection from 127.0.0.1:38481 2008.03.10 11:32:23 LOG7[18563:3086215456]: SSL state (accept): before/accept initialization 2008.03.10 11:32:23 LOG7[18563:3086215456]: SSL state (accept): SSLv3 read client hello A 2008.03.10 11:32:23 LOG7[18563:3086215456]: SSL state (accept): SSLv3 write server hello A 2008.03.10 11:32:23 LOG7[18563:3086215456]: SSL state (accept): SSLv3 write certificate A 2008.03.10 11:32:23 LOG7[18563:3086215456]: SSL state (accept): SSLv3 write server done A 2008.03.10 11:32:23 LOG3[18563:3086215456]: SSL_accept: Peer suddenly disconnected 2008.03.10 11:32:23 LOG5[18563:3086215456]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket 2008.03.10 11:32:23 LOG7[18563:3086215456]: stunnel finished (0 left) Anyone have any ideas?

Windows FIPS compile
by Joe Kemp 10 Mar '08

10 Mar '08

I am trying to get stunnel to compile against a fips openssl. I read in install.fips that it is not yet supported. Is anyone currently working on this? If so I would love to join forces or any info on the specific issues would help get me started. Thanks. -Joe
